❖ To replace sample compartment windows
1. Turn off the spectrometer.
Note If your instrument is purged, leave the purge on while you replace the windows to prevent
ambient air from entering the spectrometer.
2. Remove any sampling accessory from the spectrometer.
3. Remove the first installed window.
a. Line up the three ribs on the window replacement tool’s inside rim with the notches in the outside
rim of the first installed window.
Note The window fittings are tight. Use one hand to stabilize the instrument and the other to
remove the window.
b. Press firmly on the tool and turn it counterclockwise to loosen the window.
Continue loosening the window until it is free. If you tip the tool upward, it will support the window
so you don’t have to handle it directly.
